1998 GMC 4x4 Suburban - Clicking noise when excellerating

I have been hearing a clicking sound when I excellerate and cannot figure what is making the noise. I have taken the rear wheels off to check for any problems. Found nothing. Checked the rear differential & transfer case for low oil. Found to be ok. Placed car on jacks and ran the rear wheels, but could not hear the noise. Can only hear it when there is weight on the wheels. Checked all the U joints and they appear to be ok. Not sure if it is a problem within the rear differential or the transfer case. I did replace the transfer case several years ago(used one). Any way to identify what or where the noise is coming from? I have not checked the front breaks, but don't beleive the noise is from the front.

I assume you are trying to talk about the console? Clicking which goes along with driving and increases in frequency in proportion to speed is usually a wheel bearing or CV joint.

When excellerate I can hear a humming noise until I reach a certain speed or release the excellerator

It sounds like you may have a wheel bearing going out. If you can try to isolate the noise it will help. We are starting to see the wheel bearings go out on these models. It could be front or rear. If you need any more help or need hel locating the parts please let me know.
